Everything below comes from what CRRC Zhuzhou Institute publishes about the High Voltage Cascade System: the datasheet, the product page and press releases. Where a figure is not published, the field says so — we do not estimate.
Variants
Energy figures are nominal (beginning of life) as published by the manufacturer. One model, several duration options — the same enclosure with different power ratings.
| Variants | Energy | Power | Duration |
|---|---|---|---|
| 40 MW / 40 MWh, 35 kV (1C, 11 compartments) | 40 MWh | 40 MW | 1 h |
| 25 MW / 25 MWh, 35 kV (1C, 21 compartments) | 25 MWh | 25 MW | 1 h |
| 15 MW / 60 MWh, 35 kV (0.25C, 21 compartments) | 60 MWh | 15 MW | 4 h |
| 15 MW / 30 MWh, 35 kV (0.5C, 21 compartments) | 30 MWh | 15 MW | 2 h |
| 20 MW / 40 MWh, 35 kV (0.5C, 21 compartments) | 40 MWh | 20 MW | 2 h |
| 16.67 MW / 33.34 MWh, 35 kV (0.5C, 30 compartments) | 33.34 MWh | 16.67 MW | 2 h |
